Two generations of a wideband low noise amplifier (LNA) employing noise canceling principle have been synthesized. The first generation design was fabricated in a 0.35 µm SiGe BiCMOS process. It has a measured peak S21 of 17 dB and noise figure less than 3 dB over a bandwidth of 2.6 GHz while consuming 32.5 mW of power from a 2.5 V supply. The calculated figure of merit (FOM) is better than many reported wideband LNAs, including a few from even more advanced processes. The synthesis design constraints were improved based on the analysis of the first generation design. A second generation design was synthesized with the updated constraints. Its simulation results show that its FOM is better than its predecessor.
